The house Esperanza is looking for could be a real house, a good looking building with a big nice door that only she could lock and unlock. But, it could also be a metaphore. The one thing she wants to find is another way to be. She doesn't want to accept that the only way she could change her social class would be by marrying a rich man, she rejects the ideea of being submissive to a brutal husband as some of her friends are, and she totally hates the ideea of having to raise children in a place where she would always feel an outsider. The life she has on Mango Street and everything that follows doesn't look very promising for Esperanza. Unless she finds her way she would end up like all the other miserable characters in the book.
